If you have a few users and many databases, and the user that created the
database will be the one to access it, it might work for you to do a query
on pg_database to get a list of databases and their creators, then do a
pg_dump of each database while passing the password (echo <password>
redirection or expect script) for each database depending on the user. (I
something similar in MySQL, though not the password pasing, and it looks
like it can be done in pSQL also).

Alternatively, it seems you might run pg_dumpall as the superuser and after
dumping all the databases, chown the dump files?
